Razor



Patented Oct. 11, 19 32 UNITED STATES PERGE R. GALT', OF MERCHANTVILLE, NEW JERSEY RAZOR Application filed April 16, 1932. Serial No. 605,585.

This invention relates to a razor and more particularly to a razor of the safety type .having a double-edged blade in which a movement is imparted to the blade to facilitate shaving.

In the ordinary safety razor the blade is moved during a cutting operation at substantially a right angle to the cutting edge. The cutting effect may be considerably enhanced by moving the razor at anangle to the cutting edge so that a slicing action is obtained. It is the broad object of the present invention to produce a movement of the blade in the direction of its cutting edge so as to effect automatically this slicing action.

The present application relates primarily to a construction forming an improvement over that disclosed in my application Serial No. 573,039 filed November 5, 1931, of which the present application is in part a continuation.

Detailed objects of the invention relating particularly to features of construction will be apparent from the following description read in conjunction with the accompanying drawing in which: 7

Fig. 1 is an elevation of a razor embodying the preferred form of the invention;

Fig. 2 is a section taken longitudinally through the blade;

Fig. 3 is an inverted plan view of the same with the cover removed and certain parts broken away and in section;

Fig. 4 is an end elevation of the razor; and

Fig. 5 is a section taken substantially on the plane indicated by 55 in Fig. 2.

'The handle of the improved cated at 2, this handle being internally threaded to engage the upstanding threaded post 4 secured to the holder 6. This holder is preferably of a light metal such as an aluminum casting and is formed to provide suitable mounting for the various parts as wlll be more particularly apparent hereafter.

A suitable slot in the holder 6 provides a mounting for a slide 8 which is arranged to have a limited oscillatory movement, being held in position on the holder by the head of a screw 12, the shank of which passes through an elongated slot 10 in the slide.

razor is indi- At one end the slide carries an inwardly directed pin 14 engaged within an opening in a transverse lever 16 the ends of which engage within suitably shaped grooves in earns 18 carried by rotary members 20 which are adapted to engage the face of the user. These rotary members are preferably provided with knurled surfaces so that a frictional engagement with the face is obtained.

As either of the rotary members revolves the cam carried thereby by engagement with the corresponding end of the lever 16 causes such lever to fulcrum about its engagement with the other cam as a pivot and thus produces a movement of the pin 14 and the slide and blade secured thereto. By reason of this construction it will be obvious that either of the rollers may take control of the oscillatory movements'of the slide without interfering with the other. That is, the oscillatory movements take place without the necessity of having rotary movements of both of the members 20.

To secure the blade to the slide 8 there are provided two members 22, each of which is provided with a head 24 partially circular for reception within the usual circular por tion of a blade opening and partially elon gated sothat while the elongated portion will pass through the in one position it may be turned through a right angle to clamp the blade when the assembly is completed. The members 22 are provided with shanks pivoted in the slide 8 and carrying at their inner ends heads 26 between which and the inner surface of slide 8 are spring washers 28 which tend to clamp the heads 24 against the outersurface of the slide. By reason ofthis arrangement and the fact that the slide is provided with a plain outer face, the blade is held in flat condition rather than in the arcuate condition usually assumed in razors of conventional type. It is found that this arrangement ofelongated slot in the blade the blade is particularly advantageous in the razor herein described.

A cover 32 is provided at one side with ears whereby it is pivoted to the holder in position covering the blade except at the blades cutting edges. Suitable cars 36 are lUU provided at the other side of the cover resiliently engaging lugs38 to normally old the cover in position covering) the blade. When it is desired to change the lade the engagement between the ears 36 and the lugs 38 is readily broken by the application of moderate force. It is to be noted that the longitudinal edges of the cover closely approac the rotary members 20 providing restricted openings through which the'cutting edges of theblade projec Inasmuch as when the razor is in use the skin extends from one of the rollers 20 across the restricted opening to the cover 32, it will be obvious that with proper dimensioning only the necessary proection of the blade;will result so that while proper cuttin ofthe hairs is permitted, danger of cutting the skin will be minimized. It will be obvious that numerous modifications may be made without de arting from the spirit of the invention as efined by the following claims.

What I claim and desire to Letters Patent is: g i
